ImageMagick, RMagick, Debian installation

You want to use the rmagick gem in your ruby on rails project, but you need to install the imagemagick first.

If Imagemagick is not already installed, use the following to install it:
$ sudo apt-get install imagemagick$ sudo apt get install libmagick-dev libmagickwand-dev

You should then be able to install and use the rmagick gem
